Problems solved by technology

These patents have achieved a good solution to the above problems, but the number of arc extinguishing gas pellets placed inside the arc extinguishing device in these protection devices is limited, resulting in a limited number of operations. If it is installed in a minefield, it is necessary to repair the arc extinguishing device Frequent replacement will greatly increase the maintenance cost; and if more arc extinguishing gas pills are to be placed in the arc extinguishing device of the current structure, in order to ensure the smooth progress of the bomb replacement, specific power components (such as coil springs) must be installed. etc.), which undoubtedly increases the complexity of the structure of the arc extinguishing device, and at the same time increases its maintenance cost to a certain extent

Abstract

The invention discloses a rail sliding type arc extinguisher. The rail sliding type arc extinguisher comprises a magazine (1) and an arc extinguishing cylinder (6), wherein a triggering coil (3) and an arc guide fitting (9) are arranged inside the magazine (1); an arc guide electrode (8) connected with the arc guide fitting (9) and a gas pill triggering position are arranged at the bottom of the magazine (1); a side surface electrode (5) is arranged on the sidewall of the gas pill triggering position, wherein a spiral suspended rail (2) from top to bottom for bearing an arc extinguishing gas pill (4) is arranged on the inner wall of the magazine (1), and a groove matched with the spiral suspended rail (2) is formed in the surface of the arc extinguishing gas pill (4) which is mounted inside the magazine (1). The rail sliding type arc extinguisher is simple in structure, safe and reliable; the arc extinguishing gas pill inside the magazine is capable of sliding down smoothly only under the action of the gravity, and therefore, the step of pill changing after once triggered arc extinguishment is realized.

Description

technical field [0001] The invention belongs to gas arc extinguishing and lightning protection equipment, in particular to a track sliding arc extinguishing device. Background technique [0002] Lightning protection of transmission lines has always been an important part of the lightning protection work of the power sector, and lightning faults are still one of the important factors affecting the safety of the power grid. The impact flashover caused by lightning strike on the transmission line will cause the line insulator to flash over, and then generate a large power frequency continuous current, damage the insulator string and fittings, and cause a line accident. The traditional "blocking" lightning protection method cannot fundamentally solve the lightning strike problem due to its limitations. Therefore, the power sector generally adopts the installation of parallel protection gaps or line arresters on the transmission line to realize the protection line. However, in ...
